G. G. FLOYD CONTAINER v Original Filed July 23.' 1924 Such shaft or rod at one end has a head comprising a circular flange portion 26 inside ofshell for casing 11 and'bearingon the inner face of flange 13 and a flat, handle part 27 extended-out throughthe endopening of the element 11 and by which 'means the screw-threaded rod or shaftmay be manually, turned. 7 j V i q Along plunger or valve stem 28' slidingly accommodated in the bore of rod 25' v and at one end .in the tubular member 21 has a head 29 of, substantially the diameter ofthe hollow interior of. such member to form a cream-expelling or discharging piston and a valve for opening and closing the port 22.

The other end of the rod or valve stem 28 is fixedprsecured to a cap 31 normally covering'the'flat handle 27, as shown in'Figure3, but of course capableofsliding movement toleffect corresponding action of the plunger or valve rod 28; I V j The creamer soap tube'or cartridge 14 at one end has a follower 32 with'a thin cylindrical wall33 inside ofthe tube or cartridge a and of anou'ts'ide "diameter slightly greater than the internal diameter of the tube, whereby'a snug and non-leaking joint is maintained with the tube, such follower havingan external, central, boss 34 with screw-threads 35 on its outside and with a central, hexagonal cavity 36 designed to receive the dividedfhexagonal part 37 37 of a split-nut. 38, 38 which is internally threaded to fit the rod or shaft 25 Thecompanion parts 38', 38

1 each pivoted to a common, suitably-shaped plate 39 at/ll, tl, such plate on support hav inga central hole42'therethrou'gh of larger diameter than the threads of rod 25 so as to be freely slidable thereover.

To limitor restrictthefopening inoveinentsof the complementary nutsections 38,

V 38, each is' conveniently supplied with-Ia stop-pin 43' projecting into a recess 44 of the plate39, the, pin by engagement with an end wail of such recess acting as a stop: or abutmentjfto limit the opening or expanding 'At its other: or

movements, as shown in Figure 8. H

lnner "end, the hollow,

screw. rod 25 is fitted; with a washer or collarslig'htly 'larger in diameter than that ofthe ho1e 42 of plate 39, whereby the split-' nut cannot' be removed from therod. v

When the valve-stem Q28 isis withdrawn to its full extent, the valve or "piston 29 will occupy the position'shown in dotted V linesjin Figure'3 and'in order that the semi-- part 45 of lug 23 liquidcontents"of the tube may have access to thedischarge conduit in pipe 21', that tion is longitudinally slotted at 46'. j I ,InQactualpractice, it has been found to be convenient collapsible supply of the nut are yond its threaded portube or cartridge and its follower of pure tin with their cylindrical walls of approximately seven one-thousandths of an inch in thickness and in order that the friction between the telescoping walls of such tube and follower may be supplemented by appropriate means to insure that the follower will not turn in the tube, itis provided with a slight' outward projection at'the point 51 causing a corresponding slight projection in the outer tube at the same point,

i The operation of the appliance is substantially as follows. Assuming that the parts of thestructure are as indicated in Figure 3 and thatit is desired to project a smallcharge/of shai' ing soap or cream from" the "container or tube into 'the brush I for working up into a lather, the operator first ulls out or retracts the united cover 31' and thev'alve stem and valve 28, 29 into the dotted line position uncovering the slots iiThe n the handle 27"is given a' proper amounthf'turning'to feed the. nut37, 37 inwardly slightly which pushes the follower 32 ahead of in thcstationary cartridge,

thus expelling a portion of its semi-fluid contents into the pipeor tube 21 and possibly sonie'tlirough the valve port 22 into the brush bristles. I v

During this slight lengthwise travel of the follower, it is prevented from turning in the tube or cartridge because of its frictional fit in the latter and because of the intcrntting indentations 51. j e l Owing to the. hexagonal shape of the in tel-locking parts of the follower and nut,

the latter is also prevented'from rotation which occasions, its longitudinaltravel during the angular movement of the handle and its threaded rod'25 over whichth'enut fits.

Then the cover 31 and the valve29 and its stem 28 arepushed fully in into thefull line positions shown in Figure 3, the valve or piston 29 forcing the contentsof tube 21 j v out through the valve port- 22-into'the brush whereby'there isno small body of soap or 7 cream leftin' the brush handle and assoas it progresses inwardly. When reaches the inner end of the tube ready for use in the,

' 1 25 and in very. small degree expands thetube if or-cartrid'ge, it collapses under the pressure exerted and thus permits "a' complete dis- I charge or delivery of the tube contents.

' Assuming now thatit is desired to remove the emptiedtube and to replace it with a new filled one, we proceed as follows, understanding that such tubehas been emptied by successive movements of the parts as 53 screwed on to the threaded end 34, whereindicated above. 7 a a The hollow handle casing or sheli 11 is unscrewed from the. brush-holder'15 and re- ,moved longitudinally from the structure carrying with it the parts 27 25, 28v, 29 and the split nut 37, 37, whereupon the emptied or exhausted tube and its collapsed follower I may be unscrewed from the member 15 and thrown away.

The screw rod or shaft 25 and associated elements having been removed from the handle, the divided or split nut is then opened up or expanded and quickly slid down to the other end of the hollow, ,thread- 31 fully; home.

ed rod 25, thus avoiding the necessity l of slowly-screwing it down into place, and in itsnew position it is again contracted on to the threads of the rod 25 readyfor use.

I Each new filled tube 1 1, see Figure 2, before it is inserted in the brush-handle, has a closure 52 screwed into the tube socket 24 and at its other end the tube has a cap by the contents of the tube are always maintained infresh and proper condition and the the pair of aligned holes at the two ends of the new, filled tube, the'closures 52 and 53 having been "previously removed, and'the hexagonal socket'36 is easily. fitted over the correspondingly shaped part of the nut 37, 37, as is clearly shown ln Figure Then the threaded boss 23 of the the tube, the stem 28 and valve 29 acting as a centering guide, whereupon the handle casing 11 is applied and screwed on: to the brush-holder 15. f V Y- i The brush is now ready for use as explained above with the gradual, progressive, manual travel ofthe nut and follower in wardly to p-ress or forceout the contents of the tube, which actionfis supplemented by that of the reciprocatory plunger and valve 29. i r r It will. be observed that the part v31, when in the position shown in Figure 3, forms a cover for the flat handle 27. So far as the ueaegsei member 15 is screwed into the corresponding end' of brush iszc'oncerned, this is a feature of im p ortance', because it requires-the retraction I of the element-31, thus effecting the-"opening of the discharge,valve-port 22, before the tube-followerfcan hen-advanced bythe turning of handle 27 to deliver a portion of the soft contents. If thevalve-port rei mained closed and the handle 2-127 were turneda si-lbstanti'al amount, *there would' be a tendency to burst or-rupture.thef'soft, thin-metal tube, 'due to the fact that its soap or cream {could no t'find other egressunder V the exerted pressure.

If the. operator should fail to push "they,"

cover 31 in after it has been retracted, this is accomplished more or less automatically when he sets the brush up on its end, which action would naturally result, either ,by

pressureexerted by the operator or by the weight of the parts, incarrying' the brush handle and associated parts down sufiicient 1y to push in thevalve and {its stem cover Those skilled in this an-Q m readily understand that-this invention is not limited structual features" presented,

made in the new tube or cartridge illustrated and described without departure, from the heart and essence of the invention and without thesacrifice of any j of its substantial benefits and advantages.

3. An apertured L cylindrical thin collapsible-metal supply-tube having a cylin; drical follower closing one end of the tube and slidable therein'to expel the contentsof the tube and alsov made of thin collapsible metal, and means to prevent said follower from turning in the tube.

u 4. An apertured thin collapsible-metal cy lindrical supplytube'having a cylindrical I flanged follower slidable therein toexpel the contents of the tube and also made of thin collapsible metal, said follower being of an externaldiameter slightly greater than the internal diameter of the tube whereby tight fit therewith.
